The Cokin Creative Filter System consists of a rectangular plastic filter holder with four slots (one for Cokin rotating filters and three for rectangular ones), a variety of optional adapter rings which click into place and rotate, and many optical resin filters.

There are two Cokin sizes, "A" & "P". The "A" series is adequate for 35mm cameras and camcorders, and fits filter sizes from 36-62mm. The "P" series covers diameters from 48-82mm and is generally preferred for everything, particularly wide angle lenses. Over 100 filters and a wide range of accessories are available for each system, i.e. modular lens hoods, lens caps, and storage boxes.

Simple and effectiveThe Cokin A-series system is the most cost-effective means of adding the benefits of ND-graduated filters to compact cameras, such as mirrorless reflexes. By adding the modular lens hood units to the holder, you can have a hood for lenses that don't come with one, either factory-supplied or optional. The holder's only shortcoming is the lack of a lock on the rotational movement. Also, I find it a bit irritating that this 37mm ring, like several other A-series offerings, is only available with the filter holder, not separately. This results in a rapid accumulation of duplicate holders if you acquire a number of filters and accessories.
